In the first period of their preliminary round game, Swiss forward Simon Moser was absolutely demolished on a hit by Canadian (and Toronto Maple Leafs) defenseman Dion Phaneuf(notes). Once on the bench, he appeared to lose consciousness before being tended to by the training staff and leaving the game under his own power.

Rule 540 - Checking to the Head and Neck Area — A player who directs a check or blow, with any part of his body, to the head and neck area of an opposing player or "drives" or "forces" the head of an opposing player into the protective glass or boards, shall be assessed at the discretion of the Referee, a minor and a misconduct penalty; a major and game misconduct penalty; or a match penalty. When injury occurs, a match penalty must be assessed.

Principle point of contact appeared to be the chest, however; so Phaneuf was, and should be, in the clear.
